 abstract={The aim of this study was to evaluate the effect of high doses of calcium bentonite on the blood parameters, anticoccidial activity and intestinal histology of broiler chickens. Three undred and sixty one-day old broilers were distributed into three treatments (T+VE, T-VE, TB )with three replicates. Amprolium was added to the feed of the positive control group, calcium bentonite powder was added to the TB group, and nothing was added to the feed of the T-VE group. Coccidiosis was induced on day 14, the birds were kept until day 49, measurements of the diffe- rent variables started from week 3, blood samples were collected via wing vein, and fecal oocysts were counted from the intestinal contents of each individual bird using the McMaster techni- que. A decrease in feed consumption, body weight gain and conversion ratio was noticed in the calcium bentonite group. Broilers in the calcium bentonite group (TB ) and negative control group (T-VE ) showed clinical signs of coccidiosis (blood in feces) and the number of oocysts in feces increased with time. Histopathological examinations of the affected caeca also demonstrated excessive tissue damage, hemorrhage, the presence of clusters of large schizonts and merozoites in the tissue, and coccidian oocysts in the lumen. Feed conversion was highest in the T+VE group.},
